PLOW-'WHEl-L Application filed September This invention relates to an attachment for the furrow wheel of an agricultural'machine, such as a gang or sulky plow, or any other type of plow of the wheeled type.

One of the important objects of the present invention is to provide an which is of such construction as to prevent vegetations, such as weeds, long grass or the like from becoming entangled on theinside boxing or collar of the furrow wheel and winding around the axle on which the wheel is mounted between the hub and the lower portion of the standard. Ordinarily with the furrow Wheels now generally in use, considerable difficulty is experienced in preventing the winding around of such vegetation on the axle, and as a result, the furrow wheel will not rotate freely on the axle, and will drag instead of revolve, and oftentimes the vegetation which has been entangled will be impregnated with grease and sand so that it affects the boxing and collar.

One of the important objects of the present. invention is to provide an attachment which will -overcome the above disadvantages and at all times permit the revolving of the furrow wheel, the attachment being particularly adapted for use on furrow wheels and includes a collar and set screw which is provided for the purpose of regulating the distance to which the wheel may be placed or moved on the anle of the standard so as to adj ust the distance from the agricultural implement at which the furrow wheel lis to operate. i o

A further object is to provide a furrow wheel attachment of the above mentioned Character which may be readily and easily placed in position over the collar so as to protect the same and the set screw, said attachment fitting around the boxing, and being readily disengaged therefrom whenever it is necessary.

A further object is to provide an attachment of the abo-ve mentioned Character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed. y

Other objects and advantages of the invention will become apparent during the course of the following description taken in connection with the accompanying drawing.

Figure 2 is a top plan view, and

Figure 8 is a Vertical sectional view'taken approximately on line 3-3 of Figure 1.

In the drawing whereinv for the purpose of illustration is shown the preferred embodiment of my invention, the numeral l1 designates generally a furrow wheel of any conventional type, the same being, adapted to be mounted On the hub 2. Avlock nut 2' is threaded on the reduced outerv end 2? of the hub to prevent the displacement of the wheel from the hub. The innerv end of the hub is enlarged as indicated generally at 3, andv isdisposed adj acent the inner side of the wheel, asis more clearly illustrated in Fig. 1. The enlarged portion of the hub is| furthermore divided so .that the spaced Sections 4;

and 5-are formed. tAn annular flange 6 is formed on the ;outer face -of the section 4, whereas a similar fia'nge'ois formed Von the outer face of the intermediate portion of the other section 5,. The purpose of these flanges will hereinafter be more fullyl described.

The hub is ada-pted'to be rotatably mounted on the axle y8, which is formed' on the lower end of the standard 9,V the latter formmg a part of any well known type of gang or sulky plow, the axle beingdis'posed laterally withrespect to the standard. The axle extends longitudinally throughthe inner end of the hub, the .section 4; being provided with a suitable opening which registers with the longitudinally extending socket 10 formed in the section, and in which the free end of the axle is disposedThis will permit the longtudinal movement of the axle with respect to Vthe' hub. For the purpose of securing the hub on position with respect to the standard 9, there is provided the collar V11, the-same fitthe axle 8 in any adjustedi ting on the'axle and disposed between the complementaryl therefor in the collar, and engages the aXle for Sec-uring the col'lar and holding the 'same in the desired adjusted position on the axle. The collar is of a diameter less than the diameter .of .the en'larged inner end portion 3 of the hub 2 so that the outer .end of the set screw When the latter is in its locked position With respect to the ax'le W-ifll `not extend beyond the outer peripheral face of the enlarged inner end 'of the "hu'b.

With the type of furrow Wheels and inounting tlierefor now generally in use, consideriable clifliculty has been experienced 'in preventing vegetation lsuch as Weeds, tall grass, or .the 'like from Winding around the 'hub -or boxi'ng, as Well as between the secu tions o f the inner end of the hub and around the set Screw. As a result of the collection of this vegetation on the wheel, the revoilving of the Wheel on the azfile ,iS preVented, and t'hus prevents `the proper operation. of the furrow wheel -n .carrying out the purposes for 'which fit is designed. order to overcorne the above disadvantages ;and to provide a means for preventing the collection of such vegetatons around ;the L'hu'b or 'boxing, so that the fnrrow Wheel Will rotate freely on the ax1 e, "I have l;provided an attachinent which comprises asleeve or casing .desigated generafl'ly 'by the .numoral This sleeve l,includes the fcornpleinentary sem-cfircular sections '14 and 1'5 respectively which arel adapted to encircle thev Sections 4 and 15 of the enlarged p'ort'ion .V8 of the hub, and the edges Of the Sleeye Will abut the respective 'fl-an'ges 6 and '8. The section lit is secured in any suitable manner to the per'iphera'l faces of ;the Sections 4 `and '5,A so as .to provide a unitary structure and to further hold Said Sections in proper spaced relat'ion with respect to each other. 'The Goinplen'ientary sern'i-ci'rcular Sections lare provided with the interfitting 1looped portions 16 and '17 .respectiyely at one end 'for receiving the pin 18, Whereby a hinged joint is provided. In 'this lmanner, the complelnen'tary section 15 may be swnng .open .or closed in a simple and efi'icient l'manneix The opposite end of the complementary section 15 has fornred .therein 'the elongated Slot 19 for receiying the u-pwardily .disposed portion 20 formed on 'the opposite end of the other section 14, This 'upwardljy disposed port'ion 20 is bent ``back upon itse'lf to form a loop 'for receiving va suitable looking pin or key 21, the free ends 'of which engage the o-uter face of the adj'acent port-ion .of the section 15 so that the Sections of the s'le'eve AWill be- 'held in a 'locked position around the inner end of 'the hub or boxi'ng, and Will completely corer the .collar and set screw so that there Will be no jpoSsibilit-y of any vegetation coming in contact With the collar or set screw, and Wind'ing around the axle at that point.

For the purpose of retaining` a lubricant .in the hub, around the a-Xle, a felt washer '22 is associated With the outer end portion of the Section e of the cnlarged portion of the |hub in the inanner as shown more clearly in Figure 1.

The Simplicit'y i'n \\'-hich iny device is con- Structed enables the same to be readily and easily attached and Wi'll be strong and vdurab'le, as well as inexpensive in its 'manufacture.

TVhi'le I have 'shown the `preferred einbodimen-t of my inyention it is to be understood that Ininor changes in the size, sh-ape, and arrangeinent of :parts inay be resorted to Without departing froni the Spirit of the in- Vention and the 'scope of the appended clainis.
